Now the site is working!
I changed the Database Hostname in mainfile.php from localhost to the ip address and (i think) that did it.
If anyone can explain to me why that did it it would be really helpful.
One thing remains however, I still can't use phpMyAdmin - it gives me "Access Denied". I've updated the user/password and so on but it still doesn't work. Does anyone know what the problem might be?
Thanks
